Question 97/140

A Layer 2 switch supports multiple types of Ethernet interfaces. Similar to a trunk interface, a hybrid interface allows data frames from multiple VLANs to pass through. In addition, you can determine whether data frames from a VLAN sent out from a hybrid interface are tagged or untagged.

A. TRUE

B. FALSE

Correct Answer: A

Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding Hybrid Interfaces on a Layer 2 Switch:
* Layer 2 switches support different interface types, such as access, trunk, and hybrid interfaces.
* A trunk interface allows traffic from multiple VLANs to pass through, but frames belonging to the native VLAN are sent untagged, while all other VLAN frames are tagged.
* A hybrid interface is more flexible:
* It allows traffic from multiple VLANs to pass through, just like a trunk interface.
* However, you can configure whether frames for specific VLANs are tagged or untagged as they leave the interface. This feature is useful in certain networking scenarios, such as connecting devices that do not support VLAN tagging.
2. Key Differences Between Trunk and Hybrid Interfaces:
3. Why the Statement is TRUE:
* The statement accurately describes the functionality of a hybrid interface:
* It supports traffic from multiple VLANs.
* It allows administrators to configure whether outgoing frames are tagged or untagged for specific VLANs.
4. Summary:
* The statement is TRUE because hybrid interfaces on a Layer 2 switch support traffic from multiple VLANs and allow flexible tagging configurations.
